How to Make Bias Strips
Bias strips are often needed in sewing and quilt making to bind the edges of a project. They are also often used when you need to go around curved edges.
Start with a square piece of fabric. For smaller projects, your square should be at least 18” x 18” which will generate about 90” of 2 1/2” wide bias strips. A 24” square will make about 120” of 2 1/2”-wide bias strips.
Using a ruler and a fabric marking pencil, draw 45 degree diagonal lines across the square (Fig 1).
Note: It is important that the lines are at a 45 degree angle to achieve strips that are along the true bias.
Cut along the drawn lines (Fig 2).
Place two strips right sides together a a right angle. Slide ends so that small triangles are formed that extend about 1/2” from each end. (Fig 3). Pin in place.
Sew strips together beginning and ending where strips intersect (Fig 4). Press seam open.
Continue sewing strips together until desired length is achieved
